Junior Python React information

What does a Junior Python React developer do?

A Junior Python React developer is responsible for assisting in building web applications using Python for the backend and React.js for the frontend. Their duties often include writing and maintaining code, fixing bugs, and collaborating with senior developers to implement new features. They may also help with testing, troubleshooting, and optimizing application performance. Typically, they are still learning best practices and are expected to grow their technical skills on the job.

What are some common challenges a Junior Python React developer might face when working on full-stack projects?

As a Junior Python React developer, one common challenge is efficiently integrating the backend (often using Python frameworks like Django or Flask) with the frontend built in React. This requires clear understanding of RESTful APIs, asynchronous data handling, and managing state in React applications. Additionally, adapting to collaborative workflows, such as version control with Git and participating in code reviews, can be a learning curve. However, these challenges are great learning opportunities that help you improve your technical and teamwork skills.

As part of our Utilization Management (UM) team, you'll have the opportunity to contribute to modernizing and advancing technologies that directly impact patient care and clinical workflows.

As a Staff Full Stack Engineer at CVS Health, you'll serve as the technical leader for the UM squad - owning the end-to-end delivery of high-quality software that enhances clinician and member experiences. This is a deeply hands-on role: you will be writing, reviewing, and owning production code every day while simultaneously leading the squad. You'll drive all phases of software engineering, from requirements analysis to production deployment, while championing agile methodologies and engineering best practices. You will be the go-to technical authority for the squad, mentoring engineers, making architectural decisions, and ensuring the team delivers with quality on aggressive timelines.

In this role, you will:

  • Lead the UM squad technically end-to-end - setting direction, removing blockers, and owning outcomes across the full stack.
  • Actively write and contribute production-quality code daily - this is a hands-on engineering leadership role.
  • Drive UI architecture and development for the UM application, with a strong emphasis on building intuitive, accessible, and performant front-end experiences using React or Angular.
  • Be hands-on in the development process, actively contributing code and guiding junior developers through debugging and delivery.
  • Design, implement, and integrate LLM-based solutions into UM workflows, applying hands-on knowledge of ML concepts such as prompt engineering, fine-tuning, embeddings, and retrieval-augmented generation (RAG).
  • Architect and manage complex microservice frameworks, ensuring services are well-defined, independently deployable, resilient, and observable at scale.
  • Partner with product managers and clinical stakeholders to translate complex UM workflows into clear, user-centered requirements and designs.
  • Own architectural decisions across both UI and backend systems, ensuring scalability, maintainability, and reliability.
  • Perform release management and coordinate deployments across environments.
  • Champion observability, testing, and operational excellence to ensure 24/7 uptime for critical healthcare workflows.

Required Qualifications:

  • 5+ years of full stack software engineering experience, with demonstrable depth in UI/front-end development (React or Angular required) and back end services.
  • 5+ years of experience in one or more modern languages such as Python, Java, TypeScript, or JavaScript - with a track record of writing and owning production code.
  • 5+ years of experience building APIs, microservices, and modern software patterns; including hands-on experience designing and operating complex microservice architectures at scale.
  • 5+ years of experience with CI/CD pipelines, containerized applications, and UI frameworks (React/Angular).
  • 2+ years of hands-on experience with LLM implementation - including integrating large language models into production applications, prompt engineering, and working knowledge of ML concepts such as embeddings, RAG, fine-tuning, or model evaluation.
  • 2+ years of experience in the GCP ecosystem with hands-on development using BigTable, Spanner, GKE, and Cloud Functions.
  • 2+ years of experience building observable, fault-tolerant systems for 24/7 availability.
  • 2+ years of experience leading or mentoring a squad or team of engineers, driving delivery on complex initiatives.
  • 1+ year of experience gathering complex requirements and managing relationships with business and clinical stakeholders.

Preferred Qualifications:

  • Proven ability to lead a full squad independently - setting technical standards, unblocking engineers, and owning delivery - while remaining a active, contributing engineer.
  • Strong UX sensibility with experience designing workflows for complex enterprise or clinical applications.
  • Familiarity with microservice patterns such as service mesh, event-driven architecture, circuit breakers, and distributed tracing.
  • Experience with AI/ML frameworks and tooling (LangChain, LlamaIndex, Vertex AI, OpenAI APIs, HuggingFace, etc.).
  • Familiarity with all phases of the software development lifecycle (SDLC).
  • Excellent written and verbal communication skills, with the ability to translate technical decisions for non-technical partners.
